Who is Dolina?

I was intrigued by this article about the recent casting of Grant O'Rourke as Rupert in the OUTLANDER TV series. Not because of what it says about him, but because of this bit:
"Muireann Kelly is also filming for Outlander, playing Dolina."
Dolina?? Who's that? I can state definitively that there is no character by that name in any of Diana Gabaldon's books. That being the case, I see only two possibilities:
1) They're inventing a completely new character, or
2) Dolina might be a minor character who was in OUTLANDER but never mentioned by name, like the innkeeper's wife who helps Claire dress on her wedding day.
I asked Diana about Dolina on Compuserve and her response was, "I haven't the faintest idea, myself. Haven't seen that name in any of the scripts I've read so far, fwiw."
So even Diana doesn't know who the mystery woman is. And there's been no official announcement yet from anyone at STARZ regarding Muireann Kelly's casting. Unless someone involved with the production can tell us, I guess we're all going to have to wait and see. But feel free to speculate about Dolina, if you want to!
